相信许多人有所疑问，其实该产品不同于其他塑料餐具，它的成分基本没有损害物质，主要是玉米淀粉而制成的，在使用中可参考如下注意事项：

Many people may have doubts, but in fact, this product is different from other plastic tableware. Its ingredients are basically harmless, mainly made from corn starch. The following precautions can be taken when using it:

（一）加热时取下餐盒盖：

（1） Remove the lid of the lunch box during heating:

有些微波炉餐盒，比如有的盒体以5号PP制造，但盒盖却以4号PE制造，而PE是不能抵受高温。所以放入微波炉前，记得把盖子取下。

Some microwave lunch boxes, for example, some boxes are made of No. 5 PP, but the lid is made of No. 4 PE, which cannot withstand high temperatures. So before putting it into the microwave, remember to remove the lid.

（二）及时更换：

（2） Timely replacement:

餐盒的使用年限一般为3-5年，但当其出现变色、变脆、变黄的情形，应立即更换。

The service life of a lunch box is generally 3-5 years, but when it changes color, becomes brittle, or turns yellow, it should be replaced immediately.

（三）清洁到位：

（3） Cleaning in place:

有些餐盒，为了保持密封性，会在盖子上装上密封圈。但食物残渣渗入到密封圈里，就成为了霉菌的“福地”。

Some meal boxes, in order to maintain sealing, will have a sealing ring installed on the lid. But when food residue seeps into the sealing ring, it becomes a blessing for mold.

建议每次清洗时，把密封圈及其沟槽清洗干净，晾干后，再装回盖子上。

It is recommended to clean the sealing ring and its groove thoroughly during each cleaning, air dry them, and then reinstall them on the cover.

（四）不盛放会加速餐盒老化的食物：

（4） Not storing food that can accelerate the aging of the lunch box:

如果一次性玉米淀粉餐具内长时间存放酒精、碳酸饮料、醋等酸性物质，容易加快老化。所以，如果您家有自制的醋泡花生、杨梅酒等，记得不要放在玉米淀粉餐具里，不妨换成玻璃器皿储存。

If alcohol, carbonated drinks, vinegar, and other acidic substances are stored for a long time in disposable corn starch tableware, it is easy to accelerate aging. So, if you have homemade vinegar soaked peanuts, yangmei wine, etc. at home, remember not to put them in cornstarch tableware. It's better to replace them with glassware for storage.

（五）一次性塑料外卖盒不建议反复使用：

（5） Disposable plastic takeout boxes are not recommended for repeated use:

现在很多外卖盒，看着质量较好，标注的也是比较好的材质，有些人就忍不住洗干净囤在家里重复使用。其实这是不对的。

Nowadays, many takeout boxes look good in quality and are labeled with good materials. Some people can't help but wash them clean and store them at home for reuse. Actually, this is not right.

出于成本控制等原因，通常一次性餐盒没有较高的标准，其制作出来的目的，就是盛装一次、温度较高的、可能有油的食物，在这个条件下使用，是的。但如果使用次数较多，就会破坏一次性玉米淀粉餐具稳定性，其中的有害物质析出，长期下来可能会影响身体

Due to cost control and other reasons, disposable meal boxes usually do not have high safety standards. The purpose of their production is to contain once, hot, and potentially oily food. It is safe to use them under these conditions. But if used frequently, it will damage the stability of disposable corn starch tableware, and harmful substances may precipitate, which may affect the body in the long run
